This invention relates to printing equipment, and more particularly to a method of and mechanism for use in transferring writings or printed matter from one sheet to another.

Ihe object of the invention is to provide a transfer mechanism which includes a manually Operable body member that is adapted to be moved into engagement with a page having printed or written matter thereon, whereby the body member can then be used for transfering the printed matter or writing to another sheet or page, such as a page in a permanently bound book.

Another object of the invention is to provide a transfer mechanism which includes a body member, the body member including a handle for facilitating the manual movement thereof, the mechanism of the present invention effecting a great saving of time and expense in transferring writings, as for example in transferring printed or written matter from pages of a loose leaf notebook to pages of a permanently bound book.

Still another object of the invention is to provide a method of and means for transferring printed or written matter from one sheet to another, the sheets adapted to be supported on a base and wherein a gelatine strip is moved into engagement with a sheet having wet ink thereon whereby the gelatine strip will pick up the printing or writing, so that the sheet can be removed and replaced by a second sheet which will receive the printed matter from the gelatine strip.

A further object of the invention is to provide a transcribing machine which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same:

Figure 1 is a top plan view of the transcribing machine, constructed according to the present invention;

Figure 2 is a sectional View taken on the line 2-2 of Figure 1;

Figure 3 is a fragmentary end elevational view of the machine of the present invention;

Figure 4 is an enlarged side elevational view of the carrier member;

Figure 5 is a fragmentary plan view showing the adjusting members;

Figure 6 is a sectional View showing certain constructional details of the machine;

Figure 7 is a fragmentary perspective view of the gelatine strip;

Figure 8 is a fragmentary top plan view showing a modified transfer mechanism; and

Figure 9 is a sectional view taken on the line 9-9 of Figure 8.

Referring in detail to Figures 1 through '7 of the drawings, the numeral 30 designates a base which may be made of any suitable material such as aluminum, and the base 30 includes a horizontally disposed bottom wall 3|, and extending upwardly from the bottom wall 3| and secured thereto or formed integral therewith is a pair of vertically disposed spaced parallel end walls 32, Figures 1 and 2. Extending between the end walls 32 is a pair of side walls 33 and 40, and a pair of handles 34 are secured to the base 30 so as to facilitate the lifting up or moving of the apparatus from one place to another. Secured to the bottom wall 3| is an angle iron 35 which may be used for supporting the body member shown in Figures 8 and 9 as later described in this application.

Extending upwardly from the base 30 and secured thereto is a pair of inclined arms 36 which have a stop member 3'! extending therebetween and secured thereto. The stop member 31 is adapted to limit swinging movement of a plate 29 which is hingedly connected to the side wall 49 y hinges 39. A book having a plurality of pages may be positioned in the base 30 on either side of the plate 29. A platform 38 is adapted to support a sheet or page thereon and the platform 38 includes a lower layer of aluminum 4|. Arranged above the layer M is a fabric layer 42 which may be made of felt, while positioned above the layer s2 is an aluminum layer 43, all as best shown in Figures 2 and 9, and a resilient layer 28, which may be rubber. A pair of spaced parallel horizontally disposed tracks 44 may be arranged above the platform 38, and the tracks 44 are adapted to be engaged by wheels 45 which form part of a carrier member 48. A plurality of coil springs 47 are interposed between the platform 38 and the bottom wall M for support ing the platform. The plate 29 is provided with a cut-out 2i so that the gelatine can engage the sheet of paper.

The carrier member it includes a pair of supports 48 which have a handle as extending therebetween whereby the carrier member at can be reciprocated. Supported by the carrier member (it is a spring pressed drum 5t, there being a clamp at having locking screws 52 for maintaining the drum to in place. A gelatine strip 53 is trained over the spring pressed drum 553 and the gelatine strip 53 is adapted to be moved into engagement with a sheet having wet printed or Written matter thereon whereby the gelatine sheet 53 will pick up this material. The sheet having ink thereon is interposed between the plate 29 and the platform 38. Also carried by the member 46 is a roller 54 which serves to urge the gelatine strip 53 into engagement with the sheet arranged therebelow. One end of the gelatine strip 53 may be positioned in a cut-out 55, Figure 4, and the cut-out 55 may be arranged in the plate 29. A suitable clamping bar 56 is provided for maintaining the end of the strip 53 secured in the cut-out 55. A suitable roller may be provided for smoothing out any wrinkles which may be arranged in the gelatine strip 53. Thus,

by running a roller member over the gelatine strip 53, any air which may be below the gelatine strip will be forced therefrom.

For insuring that the plate 29 is properly aligned or held steady, a wing nut assembly 61 is provided, and also a plurality of manually operable clamps 62 are provided. Each of the clamps 62 includes a ribbed shaft 63 which has a worm 66 arranged in engagement therewith. A stem 64 extends from the worm 66, and a knob 65 is provided for rotating the stem 6%. A cable or wire 61 may be secured to the lower end of the shaft 63, so that by rotating the knob 65, the shaft 63 will be rotated to thereby apply tension to the cable in order to insure that the plate 29 is properly aligned.

Referring to Figures 8 and 9 there is shown a modified transfer mechanism. The mechanism shown in Figures 8 and 9 includes a body member 68 that may be made of a single piece of material that is provided with a pair of side walls or sections 62 which are arranged in spaced parallel relation with respect to each other. A handle 79 is provided for rocking the body member 68, and arranged below the handle 79 is a curved bottom section "it. A plurality of gelatine strips H are arranged contiguous to the lower surface of the bottom section 15, and the gelatine strips '1"! are adapted to be held in place by spring members 12. Clamps '13 are arranged in engagement with the ends of the gelatine strips 3!, and suitable spaced openings it may be provided in the clamps 13, Figure 7, whereby the ends of the spring members T2 can extend therethrough. A pair of guide members i l are supported above the platform 39 and the guide members H5 are adapted to be engaged by T-shaped elements H which are carried by the body member 68. The guide members 74 serve to limit rocking movement of the body member 68. Thus when using the mechanism shown in Figures 8 and 9, a sheet such as a sheet having wet ink thereon may be positioned between the gelatine strips Ti and the platform 35 and then the body member 68 can be rocked back and forth by means of the handle 79. This will cause the wet ink which may be printing or written matter to be picked up by the gelatine strips ll and then the sheet can be removed and replaced by a second sheet which will receive the printed matter from the gelatine strips on the body member 68.

In using the apparatus shown in Figures 1 through 6, a sheet or page having printed or written matter thereon is supported on the platform 38. Then, one end of the gelatine strip 53 may be anchored to the platform as shown in Figure 4, and the carrier member 46 can be moved back and forth across the platform 38 by means of the handle 49. This will cause the gelatine strip 53 to be unrolled from the drum 50 and the gelatine strip will engage the wet ink on the sheet to thereby pick up or receive the imprint from the sheet. Next, the first or original sheet which has been arranged on the platform 38 is removed and replaced by a second sheet and the gelatine strip 53 is now moved into engagement with the second sheet so that the printed matter will be transferred to the second sheet. The second or last named sheet may be a page or sheet of a permanently bound book, and the book may be supported in the base 38 on either side of the platform 38, depending upon which side of the page is to receive the imprint. Instead of using the carrier element 46, the body member 68 of Figures 8 and 9 may be used. Thus, the first sheet having wet ink thereon is supported on the platform 38 and then the body member 68 is rocked back and forth by means of the handle it. This causes the gelatine strip 1| to pick up the impression from the sheet, and then the first sheet is removed and replaced by a second sheet. Again the body member 68 is rocked back and forth across the second sheet so that the imprinted material will be transferred from the gelatine strip to the second sheet. The sheets are arranged below the pressure plate 29.

A roller may be used for smoothing out the gelatine strip and the drum 50 may be spring wound so that it will maintain the gelatine strip under proper tension. The gelatine strips can be used over and over again if desired. The various parts of the base may be secured together by any suitable means such as adhesive. The method of and means of the present invention is especially adapted to be used in those localities wherein printed matter or written matter is to be transferred from loose leaf pages to leaves or pages of a permanently bound book. By means of the method of and means of the present invention, there will be effected a great saving of time, effort, and money. Also, suitable molding can be arranged around the base 39 to enhance the attractiveness thereof.
